- Аннотация: For the first time, landscapes formed at functioning and abandoned sugar waste treatmentareas (Kursk region, forest-steppe Chernozem zone) have been studied. In Russia, industrialproduction of sugar from sugar beets was widely established in the early 19th century. Sugarproduction wastes discharged into specially constructed dump and sump systems contained lime,organic matter, nitrogen, phosphorus, potassium, as well as an admixture of other elements. In thesecond half of the 20th century, the development of non-waste technologies led to the abandonment of many waste storage areas. However, despite new technologies, wastewater treatment facilities are still required, and together with abandoned sites form a significant part of the local landscape in the regions of the sugar industry. For more than 50 years, landscapes haveformed with a specific regular relief, seasonal watering-drying of settling ponds, displacement ofnative species by thickets of highly invasive boxel maple (Acer negundo), dense reed (Phragmítesaustrális) and tall grass. Strongly alkaline soils, rich in organic matter, were formed. Soilscape isalso complicated by fields and plantations treated in the past with sugar production wastes thathave changed the properties of soils, while increasing their fertility. Newly formed soils are nottypical for zone of leached and typical chernozems and grey (forest) soils; they do not fit into thecells of the Russian classification (2004) and their position in the international classification (WRB)needs to be clarified. New formed landscapes that store large amounts of organic carbon havebecome an integral part of the environment of the sugar industry regions. Comprehensive soil,geobotanical, and landscape-geochemical studies of territories affected by the sugar industry in thepast and present have not yet been carried out. These studies are necessary to expand thehorizons of the studying anthropogenic landscapes and soils and their role in influencing localenvironment
